Scars after surgery: the biology of healing and evidence-based aftercare
Every operation leaves a scar — a biological fact, not a technical failing. Understanding the biology helps you take proper care and set realistic expectations.

Keloid Scar Treatment
You can expect the scar to sit flatter, look less red, and feel less itchy and tight, so your skin comes closer to feeling like your own again.
Is this right for you?
A keloid is a scar that grows beyond the edges of the original wound. It tends to be raised, firm, and sometimes red, itchy, or sore. Unlike a hypertrophic scar, which is thick but stays within the wound's borders, a keloid often spreads and can come back after treatment. The aim of treatment is to flatten, soften, and ease your symptoms, not to erase every trace.
This may be a good fit if
- You have one or a few keloids that itch, hurt, feel tight, or get in the way of daily life.
- Your scar has settled, and you want to reduce its size along with the discomfort it causes.
- You understand that keloids may need several treatment sessions and long-term follow-up to hold the results.
- You are ready to follow your aftercare plan, because this is a key part of keeping the scar from coming back.
This may not be right if
- You are hoping for a single treatment that clears the scar with no chance of return, because keloids have a notable tendency to come back.
- You are pregnant, have an infection at the scar, or have a health condition that is not yet under control.
- The scar is still very new and inflamed, in which case your doctor may suggest waiting before treating it.
How it works
Everything starts with an in-person visit. Your doctor will look at the scar and ask when it formed, what symptoms you notice such as itching or pain, your personal and family history of keloids, and any earlier treatments you have had. From there, your doctor will talk through the options that suit you and what you can realistically expect.
Depending on the size and location of the scar, treatment is often done under local anesthesia, meaning only the skin being treated is numbed while you stay awake. For larger scars or several sites, your doctor will advise on the type of anesthesia that fits your case.
Keloids are usually treated in more than one way, and sometimes these are combined: injecting medicine into the scar to soften and gradually flatten it, surgically removing the raised part of the scar, or adding supportive measures such as pressure dressings and silicone sheets. Your doctor will choose the approach based on the features of your scar.
When surgery is needed to remove the scar, your doctor takes out the scar tissue and closes the wound carefully to reduce tension on it. Because cutting alone can easily let a keloid come back, your doctor usually adds further measures after surgery to prevent return and schedules follow-up visits with you.
Realistic expectations
The realistic goal of treatment is to make the scar flatter, softer, and more comfortable, while lowering the chance that it grows back. It helps to think of this as a process that needs follow-up, not a one-time fix.
What this will not do
- It will not erase the scar completely; skin that once had a keloid can still differ in color or texture.
- It will not fully rule out a return, because the tendency to form keloids stays with each person.
- It will not replace home care; much of the long-term result depends on how closely you follow your aftercare instructions.
Recovery
Recovery varies depending on whether you have injections, surgery, or a combination, as well as on where the scar is. The milestones below are general guides; your doctor will give you a specific schedule for your case.
- The first few days
- The treated area may swell a little and feel slightly sore or tight. If you have had surgery, you will need to keep the wound clean and dry as instructed.
- Around 1 to 2 weeks
- The discomfort eases over time. If you have stitches, they are usually removed within this window.
- Around a few weeks to a few months
- The scar begins to soften and flatten gradually. With injections, your doctor may schedule several sessions a few weeks apart.
- Long-term follow-up
- Because keloids can return later on, you should come back for regular check-ups over several months so your doctor can assess the scar and step in early if needed.
Risks & safety
Every treatment on a keloid carries risks, and it matters that you understand them clearly before you decide. Your doctor will go over these points in detail based on your specific situation.
- Recurrence: a keloid can grow back, sometimes larger than before, especially when it is only cut out without combining preventive measures.
- Skin color changes in the treated area: the skin may turn darker or lighter than the surrounding skin, and this change can last a long time.
- Dimpling or thinning of the tissue at the injection site, which can happen when medicine is injected into the scar.
- Pain, swelling, or discomfort that lasts longer than expected at the treated area.
- Wound infection, which needs prompt care following your doctor's instructions.
- Uneven results between areas or between sessions, sometimes needing further visits to improve.
How we do it
At The Gioi Dep, our doctors approach a keloid as a condition to follow over time, not just a single procedure. Your doctor takes the time to examine the features of your scar, ask about your history and symptoms, and then suggest a treatment plan that you understand and agree to.
Because keloids return easily, the team focuses on a clear plan for follow-up after treatment and clear home-care guidance. You will know what to do, which signs to watch for, and when to come back, so we can step in early if the scar starts to grow again.
Frequently asked questions
Does keloid treatment hurt?
Most treatments are done after the skin is numbed, so you feel little pain during the procedure. Afterward the area may feel slightly sore or tight for a few days, and your doctor will guide you on how to ease the discomfort.
After treatment, will the scar be gone completely and as flat as normal skin?
The goal is to make the scar flatter, softer, and less symptomatic, not to erase every trace. Skin that once had a keloid can still differ slightly in color or texture.
Do keloids come back?
Yes, a keloid can return; that is part of the nature of this kind of scar. Combining several measures and following your aftercare lowers the chance of recurrence, but it does not rule it out entirely.
How many treatments will I need?
This depends on the method and how your scar responds. With injections, your doctor usually schedules several sessions a few weeks apart. Your doctor will discuss the expected number of sessions with you after the exam.
How long do I need to take off work?
Many people return to everyday activities fairly soon, especially with injections. If you have surgery to remove the scar, the time off depends on the location and extent; your doctor will advise you specifically.
Will the treatment leave a new scar?
Any treatment on the skin can leave a mark. For someone prone to keloids, this is worth weighing carefully, and your doctor will use measures meant to lower the chance that the scar grows back.
I am older now; can I still be treated?
Age is not a reason to rule treatment out. What matters more is the state of the scar, your general health, and any other conditions you have. Your doctor will look at the whole picture to decide which approach suits you.
My scar is itchy and sore; can treatment help with that?
Itching and soreness are common symptoms of a keloid, and treatment is often aimed at calming these very feelings. Many people find the itching and tightness ease once the scar is softened.
Does a small keloid need treatment?
Not necessarily. If the scar does not bother you and you are not concerned about it, simply keeping an eye on it is a reasonable choice. The decision to treat depends on how much it affects you.
